Aerosol opacity Archives

Left: Temperature-pressure profiles for a suite of irradiated hot atmospheres, from the EGP+ model suite (Fortney et al. 2008) to demonstrate the parameter space. Right: Corresponding eddy diffusivities Kzz for the various atmospheres using the methods of Saumon & Marley (2008). All models are solar metallicity. The upper part of the atmosphere where Kzz reaches a minimum and then increases as the inverse of the gas density is highlighted for the coolest atmosphere (green line) as the grey chalked line. We assume aerosol transport via Brownian motion above this region where Kzz transitions to nearly isothermal, the exact pressure of which depends on the specific temperature structure. -- astro-ph.EP
